Okay not that we've completed our menu categories page. Let's take a look at the mock up as to what would happen if the user clicked in one of these menu categories in the menu categories page. Well what would happen is that they would go to that single category page that would have all the menu items. That this category contains. Let's go to the single category page and take a look here. So we have the name of the category up front. Maybe some information underneath. And every single item here in that particular category. Notice that the layout here is one menu item followed by another menu item on the same line and then it keeps repeating over and over. Which means this is probably going to be a bootstrap grid and we're going to divide this six in six columns. So it'll divide the width of the browser nicely. Now also notice that we have yet another grid within individual cells. So here you can see that there's about half and half again. But I would say that maybe this is a little smaller, so maybe five and seven. So basically, this is going to be one cell of the grid and this is also going to be one cell of the grid. This one is probably going to take about five columns, and this one is probably going to take about seven columns. So we have a grid within the bigger grid that contains six and six columns. Okay, so let's go back to our code editor. Well, let's first actually take a look at our main categories page. And if we click on this, this will go as you can see, to a single category. And right now, we don't have a single category at HTML, which is fine. There's actually that I noticed right now it would be nice to give some sort of education to the user that we're sitting on the menu page all ready. Right now it just looks like we're again kind of in the nowhere land. So the way we could do that is by going to our menus categories page. And I'm right now in menus categories.html. Which is located in examples, Lecture 38 after folder, and I can find my menu item right here. I should actually make it capital Menu right here, and this is that menu item, that navigational menu item. Well the way to make this stand out Is to give it a class of active. And that's a bootstrap class. And I believe we might have actually overridden this class or at least overridden some of the properties in this class to match kind of the hover over effect. So let' s go back to our browser. It has a nice indication that we're sitting on the menu page. And it's the same time of background that we get and have over of other pages. Okay, so that's good. So let's go back to our code editor and copy the menu categories page because all the pages is going to be again the same except for the main content. So if we scroll down, let's close up this menu, the images. Let's go to the menu categories page and what we'll do is we'll click duplicate, and we'll change that to single category. Single category. Okay, so now it's a single category. Okay, so now what we need to do is we need to clear out all the menu categories related content out of this so we have a clean slate to start with. So we'll probably need to get to main content right here. So we'll go all the way here and find where the main content ends.
Right there. That's easy to see. And we'll erase all that. So here's our clean slate that we can start coding. Let's go back to the browser and take a look as to what happens now. If I click on one of the menu categories, it should go to single category.html and sure enough, it does accept of course, there's no content here in the middle. So let's go back to the code editor and start coding up our content. So the first thing we need to do is give our page some sort of a heading. So the way we're going to do that is by having NH2, and we're going to give it an ID so we can nicely target it later of menu categories categories title.
Okay menu categories title, and class we're going to give it text center so we'll want to center this thing, and the title is going to be something like lunch menu. And this is something that's probably going to change or definitely going to change from category to category. Now every single category is going to have some sort of a sub section where we're going to list some kind of message about this particular category. So I don' know what that is is going to be for lunch menu but I do know that I want to text center it. So I don't know what's going to be here but I don't know maybe something like lunch is not served until after 1 PM. Okay so let's say that's what we're going to say let's go back to our browser so I have the title of the page, and it's a secondary title H2 because the first title is obviously David Chu's China Bistro. And it says lunch is not served until after 1 PM. That's good enough for me. Okay. The next thing we need to do is start coding this layout here, which is about six here and six here. And I would assume that this is the type of layout when I have up through the medium type of size of the screen. And the second it gets too small we're probably going to want to stack these one up on the other. So the first thing is to have these things right here inside of a grid. So the way we start a grid is we're going to need a row. Well what we're going to do here is we're going to code up a section. So we're going to use a section tag, and within the section, is going to be our grids. Which means, the section itself is going to need class = row. Okay, now why didn't I put this in the container? Well the reason I didn't put this in a container, because it's already sitting inside of a container, which is our main content right there. Okay, so let me cut and paste some code that I prepared from before this lecture to kind of flush out the grid itself, this grid cell. And it's' a little bit evolved so let me go over it in a bit more detail. So first of all we know that the actual cell we want the cell to be about half the screen, or not about exactly about half the screen. And that's why we're saying colon medium screen, medium screen 6, which means that the second it gets to small screen, these tiles will start stacking one upon the other. Okay, so that's really all we need for our outer, kind of a cell. But there's inside kind of a little bit more complicated than that. The inside we have another row and the reason we have another row is because we want it to sub divide the picture. Let's go back and take a look at this and zoom in a little bit. So want to sub divide this picture into one cell. And take up about five columns. And the other part where it is going to tell us the name of the dish and maybe some description of it is going to be a little bit bigger. So it's going to take about seven columns. Okay, so let's take a look here. So what we're doing is we're subdividing it. The first thing is we're going to have a row. And inside of that we're going to have a column span of 5. And the reason we chose small here is because when the screen is medium or small or large, so small, large or medium, we want these things to be horizontal to each other. So this cell should be horizontal to this cell. And, if it's smaller than that, meaning if it's extra small, I'm okay with that point to have this cell stack upon this cell. So they are basically going to be positioned one on top of the other one. Okay, so let's take a look at the picture part of this grid. Okay, first of all we going to have a DIV and we going to give it a class menu item photo, and this is something we going to over in a minute in the CSS which is give it a class. So, we could kind of style every single one on the same way. Number two is well actually give this D1. This is that number that we want to put onto the actual picture, so let's take a look here, this is the number. And this number comes directly, kind of a number code, comes directly from the restaurant's menu, so we want to make sure to keep that and kind of let it correspond to the menu itself. And the way we're going to position this, if you take a look at the bottom right over here, is very similar to the way we positioned the menu titles and the category titles, is we're going to make this item a relative, position relative, and then I position this absolutely to the bottom right, which should be fairly easy. Next thing is the image itself, well image, we're going to give it a class img-responsive. That's a bootstrap class that lets it stretch out and contract depending on the size of the screen. And we're going to give it the width of 250 and height of 150, simply because I know that that's the image size that we have. We'll give it an alt, just an item for now, and we'll dynamically fill that in later. Now notice that I'm not really using a responsive Images in the sense that I'm not really substituting this image, depending on the screen size. So I could have just made this a background image and then substitute the image depending on the screen size for the larger screen size. That would give a higher resolution lower, lower, lower and so on. And the reason I'm not doing it is because it's already a pretty small resolution as it is. And I don't think it's going to be such a big deal to load, even on a mobile device over a cellular connection. Okay, so that's our div menu, photo div. The next thing we need to do is, we need to give it some pricing. And this is something that's not shown here, but this is just simply because we didn't think of it at the time. But we want to give some pricing right underneath here somewhere for this particular item, and that's why the pricing is still sitting inside of this grid in this five column grid. Okay so the pricing is going to be just a div and we're going to give it a class menu item price give it some price. We'll isolate the unit for the particular price inside of a span so we could basically target this a little bit more specifically and make this smaller. So the price will extend out, but the unit for the portion is going to be smaller. And the same thing, second price, and again, unit for the portion. We're going to isolate into a span. Okay, and that's going to be our picture or picture with some information. The second which is going to span seven columns, and again it's going to be small because we want it to stack. If it's smaller than small which means extra small. So we want these two grids to stack one up on the other. And so what we;re doing is, we're using an h3, it's yet another subheading even lower down the line. We're giving it a class menu item title. And this is something obviously we're going to have to define ourselves. And this is the name of that particular dish, It's totally made up. I don't even know if it exists in the menu. But for now that's really all we need. We have some lorem ipsum in a paragraph right below. Again with a manual item details class that we're going to code up. And that's pretty much how we're going to finish this div right here. The div that spans the seven columns. And then we're finishing the div that spans the entire thing. The entire row.
Then we're going to close the div that is the row for those two items within that cell. And then right before we close the div for the entire cell, we're going to put in the HR that is only going to be visible using this bootstrap responsive class, visible-xs, extra small. And the reason we'll want that here is again, kind of similar to our footer, we did the same type of trick there is that we'll put in a HR just as a visual separator between the menu items. But we only want them when the menu items are going to stack one up on the other. And that's only going to happen at the xs, which is the extra small screen size. So now that the basic HTML is written we are ready to move on to styling this with CSS. And that's exactly what we're going to do in part two of this lecture.
